500px has launched a version of their app for Android devices. The app is essentially a port of their iPad app, just now on Android. This is a viewer of the 500px service, which serves as a photo sharing repository for high-quality photography. Photos can be viewed by popular images, editor’s choice, those upcoming in popularity, newest uploads, via searching for keywords, and viewing one’s own 500px images by logging in to the app. Photos can be shared directly to Twitter or Facebook from directly in the app. While the app doesn’t let users save photographs directly in the app, opening up the photo in a web browser is available â€“ make sure to respect artists’ copyrights. The app does come with nude photography, which is filtered out by default, but can be re-enabled in the settings of the app.
